| 摘要 |
The present invention relates to a support apparatus for road traffic facility installation and, more particularly, to a support apparatus for road traffic facility installation in which a crossbeam for road traffic facility mounting is prevented from sagging due to its own weight and road traffic facility weight even when not wire-supported and strong wind-based crossbeam oscillation can be buffered. The support apparatus for road traffic facility installation according to the present invention includes a support that is installed upright on a road, a pipe-shaped crossbeam that is connected to the support by the medium of a connection flange section and is installed in a horizontal direction, and a sagging prevention unit that prevents the crossbeam from sagging. The sagging prevention unit is configured to include a supporting reinforcing frame portion that is installed in a longitudinal direction at an upper side outer circumferential edge of the crossbeam; and an oscillation buffering unit that is installed in the longitudinal direction on a lower side of the crossbeam to accommodate the crossbeam and is capable of buffering strong wind-based crossbeam oscillation. |
